Something’s afoot in the first trailer for David Fincher’s upcoming mystery thriller, Gone Girl, an adaptation of Gillian Flynn’s novel of the same name. The new clip finds Ben Affleck as Nick Dunne, reeling in the aftermath of the disappearance of his wife, Amy (Rosamund Pike), amidst search parties, candlelight vigils and incessant television coverage. The mood, however, soon shifts when we’re shown shots of the couple fighting and detectives scouring the Dunne residence for clues. The clip ends with a smarmy sounding Nick telling a TV interviewer: “I did not kill my wife. I am not a murderer.”

While Elvis Costello‘s devotional “She” provides the trailer with its eerily fitting soundtrack, Nine Inch Nails frontman Trent Reznor and longtime collaborator Atticus Ross are behind Gone Girl‘s score. Over on the film’s website, you can get a taste of the duo’s latest collaboration, a serene but disconcerting ambience of woodwind-like synths. The full soundtrack and score will be available this fall; Gone Girl hits theaters on October 3rd.

During negotiations, Fincher was reportedly seeking $10 million up front in fees, as well as significant control over marketing, like he was given for The Girl with the Dragon Tattoo. But that number did not jive with the film’s studio, Sony, who are looking to be more fiscally responsible after a disappointing 2013. Fincher could re-enter negotiations, but an industry source said he would have to scale back that $10 million, calling the figure “ridiculous,” and adding: “You’re not doing Transformers here. You’re not doing Captain America. This is quality — it’s not screaming commerciality. He should be rewarded in success but not up front.”
